My Uncle and I were visiting family in Sun City, AZ. We were outside around 8:30P.M. looking at the stars, and saw a very long streak of white light. Sorta like a string. Just one. It looked like it was just floating in the sky. We tried to strain our eyes to try to figure it out. Then it just got too far away and dissapeared. We only saw it for about 20 seconds. A few minutes later, about 5 military jets from Luke Airforce base, flew by above.
